CARRY-'RON ARRANGEMENT.

To @ZZ whom t may concern:

Be it known that 1, FRITZ B. Ennsr, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use- 'ul Improvements in Carry-iron ilrrrangements, of which the following is a specifica tion.

This invention relates to a new and imf proved carry iron arrangement for railway cars or more specifically to a particular form of striking casting and associated carry iron and their Vmeans of interengagement. n

Carry irons are usually provided as separate members from the striking castings in order that they may be removed to facilitate removal of' the draft rigging or associated parts. r)Che carry irons are also subject to wear and ordinarily require replacement before the striking castings and hence should be separate elements. Heretofore carry irons have generally been retained in association with the striking casting by means oil. screws,'bolts, cotter pins, or similar small parts which are subject to breakage, or which may work loose. The use of these small parts renders the carry irons unsafe since it may come loose and work out of place and drop the draw bar and coupler. Certain other carry irons have been designed `with integral lugs adapted normally to engage portions of the striking casting. These carry irons, however, may become disengaged trom the striking casting under rough where the car is Yjolted or jerked. They are therefore :fundanientall y unsafe.

lt is an object of the present invention to provide a new and improved striking casting and carry iron assembly which is simple in construction and which avoidsthe use of any small connecting or retaining members. It is also an object to provide a structure of the character described which is simple in design and may be readily manufactured by the usual casting process. Ctherand iurther objects will appear as the description proceeds.

l. have illustrated certain preferred embodiments of my invention in the accompanying` drawings in which Figure 1 is a face view of a striking casting and carry device made according to my invention 5 Figure 2 is a plan view of the device of l! igure 1; f

Figurer 10 is a plan view of the torni of the device shown in Figure 9; K

Figure 11 is an end view of the form of the device shown in Figure 9; and, rFigure 12 is a section taken on line 12412 oi Figure 10.

The form of thev device shown in Figures 1'to `t comprises the striking casting 14 having the depending arms 15 adapted to receive between them the draw bar or coupler shank 1G. This draw barrest-s on the carry iron 17, the ends of which are supportedby the cross portions 18 of the depen ing arms 15( As best shown in Figure 4C, the arms 15 are provided with the slots 19 'above the cross pieces 18. These slots are slightly greater in depth than the depth of the carry iron 17 and its depending lugs 20, which latter normally .engage 'the inner faces ot the cross members 1S. It is to be r'noted that the depthoi" the lugs 2() is greater than the clearance 21between the upper 'face oit the draw bar 1G and the striking casting li.

The iorin oli the device shown'in the iigures from 5 to 8 inclusive comprises the striking casting- 3() having depending arms 31. The draw bar 32 passes betweenthese irons and rests upon the carry` iron 88. As best shown in Figures 6 and 8, the carry iron extends upwardly at its' endseacl1 end being` provided with a T-head 84 which head fits into a socket in the lower end of the dc,- pending arm 31. The lugs 35 engage the rear-faces of the T-head 3&1 and the openings 3G lare provided in the rear of Athe lugs 85; the openings being of sutlicient size to per mit passage of the heads 34, and the space between thelugs' permitting passage of the portion ot the carry iron below the heads 342. lt should be noted that the height of: the

lugs 35 is greater than the clearance 87 between the upperl face of the draw bar and the adjacent surface of the. striking casting. Obviously if desired the arrangement of the engaging lugs may be reversed to permit withdrawal of the carry iron from the liront.

The form or' the device shown in the iigures from 9 to l2 comprises the striking casting 4l having the depending arms 42 each provided with the lateral opening 43 and with the upwardly extending inner lip 44. The carry iron 45 has downwardly extending ends 4G itting in behind the lips 44. The carry iron supports the draw bar 47. The lateral openings 43 in the arms .42 are of sufficient size to permit the endwise applica tion and withdrawal of the carry iron. It is to be noted, however, that the distance which it is necessary to raise the carry iron 45 to permit it to be withdrawn through either opening 43 is greater than the clearance 48 between the upper tace of the draw bar and the adjacent surface of the striking casting. I y

All :terms ot' the device have the common characteristic that the carry iron is retained in place in the striking casting by the interengaging portions on these two elements which may be readily disengaged. The movement necessary for this disengagement, however, is greater than the clearance afforded between the draw bar and these parts. It is therefore impossible while the .draw bar is in place ior the carry iron to become accidentally disengaged from the striking casting, regardless of the rough treatment which it may receive in use. It is to be understood that the size of the coupler shank in the vertical directien is standardized at six inches by the M. C. B. speciiica-tions, and it is thereorepossible to construct my device with delinite clearances.

In the form shown in Figure 1, with the draw bar removed, the carry iron is simply lifted suiliciently for the lugs 20 to clear the cross pieces and it may then be removed through either opening 19, or tilted and removed from the bottom.

In the 'form shown in the Figures from 5 to 8, with the draw bar removed, the carry iron is lifted suiiiciently for the T-heads 34 to clear the lugs 35. It is then moved rearwardly'beyond these lugs and drawn downwardly out of the casting. It is replaced in the reverse manner.

In the form shown in the Figures 9 to l2 the draw bar may be raised and removed through either lateral opening 43.

It is thus seen that I have designed a carry iron arrangement such that the carry iron is positively retained in place so long as the coupler shank or draw bar is in place. Accidental or malicious removal oi the carry kiron is therefore prevented. lt has no small retaining elements which may work loose or be removed. rlhe device is extremely simple in construction and may be readily manuiactured and is adapted tor easy use.

'Vhile l have described more or less precisely the details of construction of my invention, l do not wish to be understood as limiting myself' thereto, as I contemplate changes in form and the proportion oit parts and substitution or' equivalents as circumstances may suggest or render expedient, without departing` from the spirit of my invention.

l claim:
